I assure you, there are well endowed Alpha studs out there who can give your wife more cock than you ever will.
Interesting you bring this up. Last night I don't know how we got on the topic of size, but we did. She asked how big I was and I told her I thought I was 6 inches. She remembered we had recently measured me and she looked at me with thought and said, "Are you sure?" I told her I was fairly certain I was 6 inches and she raced to get the measuring tape. She pulled my pants down and stroked me a few times to make sure to get every inch possible out of me as she measured. Deeply looking at the measuring tape she said to me, "Oh my God you better not only be 6 inches." She looked closer and as if she was doing everything she could to make the measuring seem like it was over 6 inches she said, "I think you may be a little over." She said it like she couldn't accept in her mind I was only 6 inches, and 6.1 inches would be enough to ease her mind. She even tugged it upward once to get it more over that 6 inch line. There was no previous build up talk leading into this either, this was spur of the moment somehow we got onto size talk and she said that. It was pretty hot because I was sitting there thinking, given our recent talks, is this a come to realization moment that she could get bigger and better sex?
Nothing else to really bring up, I did get lucky last night but it was as plain and vanilla as you could get. Before we began she told me, "Get over here. You better make this quick." When we were done it had taken me awhile to get her to orgasm and she said, "Made you work at that one a little bit, burn off some of your desert." I had eaten some unhealthy food throughout the night and she made me aware of it.
Again, the size discussion just left me wondering if this was a little something that clicked in her mind. I refrained from bringing up anything cuckolding because I do want to give it some time before bringing it up again, and also it just felt like I didn't have to bring up that she could get bigger if she wanted, it was as if she knew.
